Pumping brakes can help restore pressure to the brake calipers temporarily. But this method wont work if the vehicle is equipped with ABS, or anti-lock brakes. Usually, down shifting will help slow the vehicle down, but not stop completely.

Why does my brake pedal bleed done it won't hold pressure?

Probably either from air in the lines or the master cylinder leaking and in need of repair before the brakes go out entirely. To tell the difference, if you pump up the brakes and hold pressure on the peddle and it stays up and then you let off of the peddle and it goes down, it is probably air, bleed the brakes. If after pumping up the brakes and holding pressure it slowly leaks down, you are either losing fluid somewhere or the master cylinder internal seals are bad, fix them before the brakes are gone when you need them.
